-peeifieation of Letters iatent. Patigmfi gfl June ]"1@15 Application filed December 17, 1913. Serial No. 807,230.

My invention relates to improvements in railwaytie-plates, and one object is to provide a simpleand inexpensive device of this character which will securely hold a rail.

laid thereon from creeping, or rattling when a train travels thereover.

Among otherfeatuaes, the invention embodies means that antomatically take up slack between the tie-plate and the rail, so

' that the latter- 3m always held firmly upon the former.

In order that'the hivention may be fully understood, reference will now be made to the accompanying drawing, in which: Figure 1 is a cross sectional view of a rail and my tie-plate on line I-l of Fig. 2, in position upon a cross-tie. Fig; 2 is a plan view of the tie-plate and the rail, the, latter being in section on lineII-Il of Fig. 1. Fig. 3

is a detail perspective View of a locking member for securing one side of the rail and tie-plate together.

Referring now in detail to said drawing, 1 designates the tie-plate which is wider than the base of the "rail Agasshown on Figs. 1 and 2, to provide abroad bearing surface upon the underlying cross-tie B. The underside of the tie-plate is provided with a pair of longitudinal V-shaped teeth 2, which become embedded in the top of the cross-tie and thus assist spiltesC in hoiding said tic-plate in proper position. The upper portion of the tie-plate, near one side thereof, has a longitudinal flange .3 with a beveled upper surface 4. Flange 3 is adapted to abut the adjacent side of the rail base 45.

and thus prevent lateral movement of the rail A in the direction of said flange 3. The inner vertical side of flange?) has a series of teeth 5, which become embedded in the abutting edge of the rail base and thus prevent the same from creeping longtudinally upon the tie-plate.

6 designates a lip on the tie-plate adapted to overlap the opposite side of the rail base from that abutting the flange 3. Lip 6 is provided with-a centrally-disposed aperture 7 for the reception of a'tapered locking member 8 provided at its reduced end with an upwardly extendin it from being driven t rough the aperture 7. Head 9 is protected from injury'by a. pair of oppositely-disposed guard members 10 integral with the tie-plate.

In practice one side of the rail baseis placed beneath the lip 6, while the opposite side of said base is placedupon the beveled upper surface 4 of flan e 3, after which sufiicient weight is applie to'the top of the rail to cause it to slide down from said beveled surface 4: to the position shown in 1 Fig. 1. Spikes C are then driven throu ,h

openings 11 i'n' the tie-plate to, secure tie same to the underlying cross-tie and also to hold the side of the rail base abutting the flange 3.

The opposite side of the rail base is then wedged firmly upon the tie-plate l by driving the locking member 8 downward in the direction of its head 9. Owing to the tapered shape of the locking member 8 and the inclined position it occupies while in use, it will automatically take up any' slack between the tie-plate and the railand thus prevent rattling of the latter upon the former.

Having thus described my inventlomwhat I claim and desire to secure by Letters Pat-- ent is: y

In combination, a tie-plate, a lipon said tie-plate having an opening therein and adapted to overlap'one side of a rail base, oppositely disposedcent the opening in't e lip, and a tapered ard members adj ahead 9 to'prevent looking member extending throiigh the.

opening in the lip and adapted to engage the rail base.

In-testimony whereof if afiix my sigmature, 111' the presence of two witnemes.
